* Issue #8692: Improve performance of math.factorial:Mark Dickinson2010-05-151-20/+240
| | | | | | | | | | | | | (1) use a different algorithm that roughly halves the total number of multiplications required and results in more balanced multiplications (2) use a lookup table for small arguments (3) fast accumulation of products in C integer arithmetic rather than PyLong arithmetic when possible. Typical speedup, from unscientific testing on a 64-bit laptop, is 4.5x to 6.5x for arguments in the range 100 - 10000. Patch by Daniel Stutzbach; extensive reviews by Alexander Belopolsky.

The exponent produced by _PyLong_Frexp now has type Py_ssize_t instead of the previously used int, and no longer needs scaling by PyLong_SHIFT. This frees the math module from having to know anything about the PyLong implementation. This closes issue #5576. ........
